Inter pod communication using shared memory
Hi all, Is Boost supports inter pod communication using shared memory or other ways like boost interprocess communication. Looking inputs on this.

I don't fully understand your question. Are you are talking about Kubernetes pods? In this case any network communication stack will work and Boost has tools for that (Asio, Beast, etc.) Best, Ion
Yes Ion, like boost inter process, is it possible to use boost library for using shared memory between Kubernetes pods?

No, I'm not aware of any library that can do that. I don't know if that is even possible, as you need to share memory and guarantee atomic operations on memory between pods that can be in different nodes (which implies network traffic). Best, Ion
Hi all, Adding to above question, scenario details: if kubernetes pods are created in the same machine with enabling shared memory so that both pods can access this shared area. In this case, if we run one process in pod 1 and another process in pod2, and these processes are using boost interprocess to create/find class objects, STL containers. I am able to create the above scenario and run 2 pods and verified class object sharing using boost interprocess library, want to check with you all if there are any risks in using this way w.r.t performance and stability (unexpected behaviour). Are there any limitations/ design aspects that need to be taken care while using boost library ?

Hi, Glad to hear Boost.Interprocess is being used in innovative ways. If usual shared memory (/dev/shm) between Linux containers is used, then I don't expect any problem and/or performance issue because there is no kubernetes/docker software layer between Boost.Interprocess accesses to mapped memory. Usual linux kernel is managing those accesses. In any case, I've never tried using Boost.Interprocess between linux containers so I can't 100% guarantee everything will work fine. We'll try to help if something unexpected happens ;-) Best, Ion
Hi all You should not store STL containers in shared memory. Shared memory pages may be mapped to different addresses in different processes. If the STL container uses pointers to nodes (like list, map etc. do), these pointers are only valid for processes that mapped the shared memory to the address. And it is not possible to always map the shared memory to the same address. You should use the containers from Boost.Interprocess, because they store address offsets instead of pointers == addresses.
